A medical system including: an instrument having a motion that is electrically driven, the motion being forward and backward movement of an insertion section, a bending angle of a bending section of the insertion section, and/or rolling rotation of the insertion section; an operation device performing an operation input of the motion; and a processor. The processor controlling the motion based on the operation input in a motion mode, the motion mode being one of a full auto mode to perform automatic control of the motion and a semi auto mode in which an operator manually controls the motion. When controlling the motion in the semi auto mode, the processor interrupting the semi auto mode by automatic control of the motion to perform intervention, Subsequent to the intervention, the processor switching to one of the full auto mode and the semi auto mode based on a use of the instrument.

An endoscope includes a handle operation unit. The handle operation unit includes: an outer ring; a cam ring accommodated in the outer ring to rotate in accordance with rotation of the outer ring about a central axis and having a pair of guide holes; a pair of slide members accommodated in the respective guide holes and fixed to a force transmission member; and a support portion having a pair of slide grooves extending along a longitudinal direction of the endoscope, the support portion being accommodated in the cam ring to support the pair of slide members. The slide members slide in the respective slide grooves in accordance with the rotation of the outer ring. The field of view of the image-capturing unit is changed in accordance with sliding of the pair of slide members.

A detachable endoscope having a buffer function includes: an operation part for operating the front end of an insertion part having an illuminating photographing part to be bent and a detachable unit for detachably coupling the insertion part and the operation part, wherein the detachable unit includes: a first detachable module connected to the respective other ends of first, second, third, and fourth operation wires having the respective one ends connected to the front end inside the insertion part and provided on the rear end of the insertion part, and a second detachable module connected to first, second, third, and fourth connection wires of a direction conversion part for converting a rotational motion into a linear motion in the operation part and provided on the front end of the operation part.

A detachable endoscope includes: an operation part for operating the front end of an insertion part having a lighting photographing part to be bent and a detachable unit for detachably coupling the operation part and the insertion part, wherein the detachable unit includes: a first detachable module connected to first, second, third, and fourth operation wires arranged parallel to each other so that the respective one ends are connected to the front end inside the insertion part and provided on the rear end of the insertion part, a second detachable module connected to first, second, third, and fourth connection wires of a direction conversion part for converting a rotational motion into a linear motion in the operation part and provided on the front end of the operation part, and a bending control part for adjusting an angle at which the front end of the insertion part is bent and displaced vertically or horizontally.

A handle for endoscope including a handle housing, an operating member (7) accommodated in said handle housing, at least one guide tube (16) adapted for surrounding and supporting at least one pull wire (17), and an anchoring block (15). The anchoring block (15) comprises at least one bore (20) adapted for insertion of said at least one guide tube (16) and at least one inlet passage in fluid communication with said at least one bore.

A tubular connector for use with a spiral tube used on an insertion section of an endoscope. The tubular connector including: an outer surface; an inner surface; and a plurality of cams circumferentially spaced on the inner surface to project radially inward from the inner surface, the plurality of cams extending in a longitudinal direction of the tubular connector; wherein each of the plurality of cams have one or more cam surfaces configured to engage a rotating member to rotate the spiral tube. The plurality of cams can alternatively be formed directly on an interior surface of the spiral tube.

A medical system including an endoscope configured to electrically drive an endoscopic operation. The endoscopic operation includes at least one of a forward and backward movement of an insertion section, a bending angle of a bending section of the insertion section, and a rolling rotation of the insertion section, the endoscope being configured to capture an endoscope image. The medical system further includes a processor comprising hardware. The processor is configured to control the endoscopic operation to achieve a second positioning subsequent to a first positioning, the first positioning being where the insertion section is positioned with respect to a papillary portion of a duodenum, the second positioning positions a distal end section of the insertion section with respect to a papillary portion of the duodenum based on the endoscope image.

A method includes transmitting an instruction to a motive power supply of an elastically deformable device to drive the elastically deformable device in accordance with a drive setting; measuring a force exerted on the elastically deformable device with a sensor; outputting an observed value representative of the force; comparing the observed value with a reference value corresponding with a predetermined force to be exerted on the elastically deformable device; and adjusting the drive setting based on a determination that the observed value is outside of a predetermined range of the reference value. The method prevents slack in the elastically deformable device over time. Related apparatuses, systems, techniques and articles are also described.
